Biology and notes. Copestylum bulbosum is associated with native flora in highlands of the Andes. Specimens have been collected visiting flowers of Aldama helianthoides (Rich.) E.E. Schill. & Panero (R. Barahona-Segovia, pers. obs.). In Chile its habitat has been negatively affected by mining and water exploitation, reducing feeding resources for adults and habitat for its offspring. There is no knowledge of this species biology.

Conservation status. VU under B1ab (iii) + 2ab (iii) using EOO = 11,115 km 2;AOO = 36 km 2, 7 subpopulations and eight localities.
